The Quality Comparison of Hawach Flash Column with World Famous Brand for 3000g Silica Flash Column

Experiment Purpose:
The Hawach can offer big size flash columns like 3000g silicon flash column, which can be used in a large amount of loading samples. This experiment compared the Hawach 3000g flash column and the same one of world-famous brand A, demonstrating that our big size flash column has good separation.

Experiment process:

Test flash column:
Hawach StarFlash series 3000g standard silica column(40-63μm, 60Å) and the same one of well-known brand A.

Test parameters:
Sample: Acetophenone and P-Methoxyacetophenone
Mobile phase: 80% hexane and 20% ethyl acetate
Flow Rate: 250 mL/min
Sample Size: 40 mL
WaveLength: 254 nm

Experiment results:
As shown in Figure 1, the Hawach 3000g big size flash column shows a pretty good separation ability compared with brand A.
